Expert .NET Services Tailored to Your Business
From modernising legacy code to building brand-new platforms, here is how I can solve your most pressing software challenges.
Legacy System Migration
Is outdated technology slowing your business down or costing you in maintenance? I specialise in migrating legacy applications to modern, scalable .NET frameworks. Whether your system is written in VB6, ASP.NET Web Forms, PHP, or Java, I plan and execute each migration carefully β minimising downtime and risk while ensuring a clean, future-ready codebase. The result is a faster, more maintainable application that supports your long-term growth.
Performance Optimisation
A slow application costs you customers and credibility. I diagnose and eliminate performance bottlenecks in .NET web apps and APIs β from inefficient database queries and poorly indexed MSSQL tables to sluggish DevExpress UI components and bloated API response payloads. I also carry out dedicated performance audits for mobile apps built with .NET MAUI, ensuring your users get a smooth, responsive experience on every device.
Custom Website & Application Development
Every business has unique needs, and off-the-shelf software rarely fits perfectly. I build bespoke web solutions β from company CRM systems and internal management portals to high-converting marketing landing pages. I can also bring creative ideas to life, such as interactive competition mechanics like Spin the Wheel and Scratch & Win games, or full-featured live-streaming platforms.
Mobile-Friendly Website Transformation
Over 60% of web traffic now comes from mobile devices. If your existing website does not look great on a phone or tablet, you are losing potential clients every single day. I can transform your desktop-only or outdated site into a fully responsive, modern web experience β one that performs well and looks sharp on every screen size, without sacrificing your existing branding or content.
Dashboard & Business Intelligence Reporting
Raw data is only valuable when you can act on it. I design and build custom business intelligence dashboards that surface the metrics that matter most to your organisation. I specialise in secure dashboard sharing, automated report distribution, and Power BI external sharing β so the right people always have access to the right information, without the manual effort.
Business Process Automation
Repetitive manual tasks drain your team's time and introduce human error. I build automation workflows that handle these tasks for you β for example, automatically reading invoices arriving by email and pushing them into your accounting software, or orchestrating your entire e-commerce order-to-shipping pipeline without manual intervention. Enable your team to focus on work that actually moves the business forward.
MSSQL Database Design & Optimisation
A poorly structured database becomes a bottleneck that affects every part of your application. I provide end-to-end MSSQL services β from schema design and normalisation to query optimisation, index tuning, performance profiling, and zero-downtime migrations. Whether you are building from scratch or untangling years of accumulated technical debt, I ensure your data layer is solid, secure, and fast.
Automated PDF Data Extraction
Manually keying data from PDF documents is tedious, error-prone, and expensive at scale. I build intelligent extraction pipelines that automatically parse and structure data from invoices, bank statements, utility bills, payslips, purchase orders, tax certificates, and complex medical claim forms β feeding the results directly into your database or business system.
Payment Gateway Integration
A frictionless checkout experience directly impacts your revenue. I integrate a wide range of payment gateways into your website or application, including PayPal, Stripe, PayFast, Yoco, and Authorize.Net for traditional payments, as well as emerging crypto payment solutions for forward-thinking businesses.
Integrations, Security & More
My expertise extends across a broad range of integration and compliance work: client communication tools (Email, SMS, WhatsApp Business API), automated document generation (invoices, contracts, proposals), accounting platform integration (Xero, Sage, QuickBooks, FreshBooks), digital signature services (DocuSign, Adobe Sign, HelloSign), and security enhancements including two-factor authentication (2FA) and GDPR/CCPA compliance implementation.
